Yo! The surprisingly popular single-tap zero-character communication appYo has just received its first major update.
Now, the app that has earned itself quite a reputation as a virtually featureless messaging app has gained several significant features — while retaining its core capability of enabling communication with just "Yo."

Yo now also lets you attach a link to your Yo. Just copy a link from another app to your device's clipboard, open the Yo app, and tap and hold on a recipient's username to send the link as an attachment to your Yo. In line with this new feature, you can now also open a link attached to a Yo by tapping a Yo notification with an asterisk next to it.
The first major update to Yo also introduces the concept of #hashtags to the app. As noted by the Yo team in a new blog post:

Yo Hashtags are a new and easy way for people to show their love for a cause, a person, a political figure, a brand, #CATS or #DOGS, #OBAMA or #CLINTON, #THEWIRE or #BREAKINGBAD, #TECHCRUNCH or #MASHABLE, #GAYMARRIAGE, #BRINGBACKOURGIRLS, … you get the point …
